resolving Uniform Resource Identifiers.</p>
<p>A Uniform Resource Identifier (URI) is a string that uniquely
identifies a resource. URIs are versatile global identifiers. It is
often useful to transform a URI that identifies something logical
into a URI that locates something physical (a URL), or to simply
map a URI to a different URI. <a href="qabstracturiresolver.html#resolve">QAbstractUriResolver.resolve</a>()
provides this functionality.</p>
<p>For example, one could write a QAbstractUriResolver subclass
that rewrites library ISBN number URIs as book title URLs, e.g.,
<i>urn:isbn:0-345-33973-8</i> would be rewritten as
<i>file:///books/returnOfTheKing.doc</i>. Or a QAbstractUriResolver
subclass could be written for a web browser to let the web browser
protect the user's private files by mapping incoming requests for
them to null URIs.</p>

specified <i>parent</i>.</p>


<h3 class="fn"><a name="resolve" /><a href="qurl.html">QUrl</a> QAbstractUriResolver.resolve (<i>self</i>, <a href="qurl.html">QUrl</a>&#160;<i>relative</i>, <a href="qurl.html">QUrl</a>&#160;<i>baseURI</i>)</h3><p>This method is abstract and should be reimplemented in any sub-class.</p><p>Returns the <i>relative</i> URI resolved using the
<i>baseURI</i>.</p>
<p>The caller guarantees that both <i>relative</i> and
<i>baseURI</i> are valid, and that <i>baseURI</i> is absolute.
<i>relative</i> can be relative, absolute, or empty.</p>
<p>The returned <a href="qurl.html">QUrl</a> can be a default
constructed <a href="qurl.html">QUrl</a>. If it is not a default
constructed <a href="qurl.html">QUrl</a>, it will be absolute and
valid. If a default constructed <a href="qurl.html">QUrl</a> is
returned, it means the <i>relative</i> URI was not accepted to be
resolved.</p>
<p>If the reimplemented resolve() function decides it has nothing
to do about resolving the <i>relative</i> URI, it should simply
return the <i>relative</i> URI resolved against the <i>baseURI</i>,
i.e.:</p>
<pre class="cpp">
 <span class="keyword">return</span> baseURI<span class="operator">.</span>resolved(relative);
</pre>
